Protein MIIP suppresses colorectal cancer by regulating immune cell signaling

by

Colorectal cancer remains one of the leading causes of cancer-related mortality worldwide, largely due to metastasis and limited responses to immunotherapy in most patients. Although immune checkpoint inhibitors have transformed treatment for certain tumor subtypes, the majority of colorectal cancers remain “immune-cold,” meaning they fail to trigger effective anti-tumor immunity. Increasing evidence suggests that tumor-associated … Read more

Dual-positive hybrid cells linked to shorter survival in advanced breast cancer

by

An enigmatic type of circulating tumor cell called a dual-positive (DP) cell is associated with shorter survival time in patients with advanced breast cancer, according to a study led by investigators at Weill Cornell Medicine and NewYork-Presbyterian. The findings highlight the potential importance of these under-studied cells in breast cancer progression. Circulating tumors cells are … Read more

Targeted PET/CT tracer improves early prediction of treatment response in rheumatoid arthritis patients

by

A new targeted PET/CT tracer can detect treatment response in rheumatoid arthritis patients in as little as four weeks, and potentially even at the start of treatment, according to new research published in The Journal of Nuclear Medicine. Compared to the three to six months currently required to establish treatment efficacy, this new imaging technique could … Read more

Engineered Listeria boosts innate immunity against cancer

by

After nearly 40 years of research on how Listeria bacteria manipulate our cells and battle our immune system to cause listeriosis, Daniel Portnoy and his colleagues have discovered a way to turn the bacteria into a potent booster of the immune system – and a potential weapon against cancer. Three years ago, Portnoy cofounded a … Read more

IRF7 reshapes the behavior of vascular smooth muscle cells during atherosclerosis

by

Atherosclerosis underlies most heart attacks and strokes and is now recognized as a chronic inflammatory disease rather than a simple disorder of cholesterol deposition. While immune cells such as macrophages have been widely studied, emerging evidence shows that vascular smooth muscle cells also play a central role in plaque development. These cells exhibit remarkable plasticity, … Read more

Immune microRNAs drive new frontiers in cardiovascular disease research

by

  Cardiovascular diseases (CVDs) continue to dominate global mortality statistics, with immune dysregulation emerging as a central feature in their pathogenesis. This review by Gareev et al. focuses on immune-derived microRNAs (immuno-miRs) as pivotal modulators of immune responses in cardiovascular settings, highlighting their roles in pathophysiology, diagnostic potential, and therapeutic promise. Introduction … Read more

Macrophages take center stage in liver healing after injury

by

The liver is famous for its remarkable ability to regenerate, but that healing power depends heavily on the actions of its resident immune cells. A new study spotlights macrophages, the liver’s cleanup and repair specialists, revealing that these cells quickly adapt after injury to clear debris and support tissue recovery. Researchers from the National Institutes … Read more

Existing therapies may help control chronic muscle inflammation in Duchenne muscular dystrophy

by

A new study led by researchers at Hospital for Special Surgery (HSS) suggests that currently available therapies may help control chronic muscle inflammation in Duchenne muscular dystrophy (DMD), a severe condition that leads to muscle weakness and premature death. The study, published in PNAS, identifies new mechanisms that drive chronic muscle inflammation in a disease … Read more

Study links impaired synaptic pruning to autism

by

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition in which affected individuals experience difficulties in social communication and exhibit restricted, repetitive patterns of behavior or interests. A growing body of research suggests that neurobiological changes, particularly abnormalities in dendritic spines, tiny protrusions on nerve cells where synapses form, may be a hallmark of ASD. … Read more
